（1） What should be paid attention to when installing coking accessories

When installing coking accessories, it is important to pay attention to the alignment and leveling of the brick seat between the fire hole seat and the cover. Before installing the fire hole seat, it should be 0-4mm higher than the top surface of the furnace. When installing the fire hole seat, the outer surface of the seat should be cleaned first, and then the ceramic fiber rope should be wrapped around it（ φ 8mm), plaster with clay mortar, and then insert it into the brick base. Pay attention to preventing the mortar from falling into the vertical fire channel, and the top should be pointed, compacted, and smoothed. Before installing the riser base, the elevation of the base brick and the size of the brick hole should be checked first. The floor of the riser base should be flat and smooth, without protrusions, burrs, etc. The deviation between the centerline of the riser base and the centerline of the coking accessories is ± 3mm. When installing the riser base, first bond the ceramic fiber rope to the outer wall, and apply appropriate mortar to the base brick. After laying into the base of the rising pipe, the gaps should be filled with specified ceramic fiber ropes, and the surface should be coated with clay mortar.

The pressure on the resources of coking coke oven equipment is becoming increasingly prominent, and currently, mineral resources are being affected from time to time. There is a great contradiction between extensive beneficiation and resource reduction, so the market urgently needs beneficiation technology. The development of beneficiation equipment needs to be adjusted in a timely manner and developed in the right direction. Improving the utilization rate of ore and increasing the recovery rate of tailings are the key points for the future development of manufacturers. Smoothen the surface of coking accessories. Before installation, inspect the filling material layer for cracks, dross, or severe defects. Rework should be carried out. After laying the vacuum hole seat brick, surround the fixing frame of the seat brick according to the actual situation of the seat brick, weld it well, and then install the vacuum hole seat. The elevation deviation of the vacuum hole seat device is ± 12 mm. After the vacuum hole seat is adjusted, the surrounding area is filled with heat-resistant concrete and ground flat.

During the use of coking accessories, good management should be carried out to achieve good investment results. To maintain the equipment in good condition, fully utilize its efficiency, and promote the development of enterprise production. Half of the air pollution on the top of the coke oven is caused by the escape of raw gas from the rising pipe cover and valve body socket. The rising pipe of coke oven coking accessories is a device that first passes through the gas escaping from the coke oven. The cover of the rising pipe is opened before pushing the coke, and the back cover of the coal loading is installed. When the gap between the valve body and the socket of the bridge pipe is large, asbestos rope is used to block it. This is what needs to be done. The protective iron parts are also one of the main equipment of the coke oven, which is mainly responsible for protecting the bricks of the coke oven body and changing with the temperature of the coke oven.

（2） Technical requirements for installation of guide rails for coke oven accessories

The three major locomotives of coke oven accessories move on three different tracks, but the operating status of the three locomotives needs to be consistent, so information and data communication should be maintained between the three locomotives at all times. The coke pushing car, coke blocking car, and coke quenching car are all large and heavy-duty mechanical equipment. Three coking locomotives operate on different tracks, and only when all three locomotives are aligned with the same planned coke pushing furnace can each locomotive perform a series of operations such as coke pushing. Therefore, it is necessary to maintain communication of data and information between the coke pushing car, coke blocking car, and coke quenching car. The four major coke oven accessory car tracks include: coke pushing car tracks, coke blocking car tracks, quenching car tracks, and dust removal car tracks. The technical requirements for rail installation are as follows:

1. The track pad of coking equipment accessories should be firmly padded and free from looseness;

2. The centerline of each track is parallel to the installation reference line, with a limit deviation of ± 2mm;

3. The track of coke oven accessories should be straight, not twisted, and not have hard bends;

4. The expansion joint between track joints should meet the design requirements with a deviation of ± 3mm;

5. The deviation between the track elevation of each vehicle and the design elevation shall be strictly carried out in accordance with the installation regulations. The rail top elevation shall be measured every 5 carbonization chambers, and the adjacent elevation difference shall not exceed 2mm.
